"In order to obtain good quality data, it is essential to work with fresh blood samples. In the past I have ordered such samples from many suppliers, and I have found Research Donors to be absolutely the best. They offer an extremely reliable overnight delivery, a very good customer service and, most importantly, a high-quality product. They are now my only supplier for human whole blood!"

"We have been using Research Donors as our supplier of frozen human PBMC cells for over a year. The cells are always delivered promptly and arrive on the date specified at the time of ordering. Further, the viability of the cells are higher than what we have observed from alternative suppliers and the numbers of viable cells always exceeds the specification. Communication is fast, friendly, and informative and the staff were very willing to adapt the product to our needs."
